On-board information displays are essential part of passenger information systems. They inform passengers about the date, time, next stop, line and destination. The XID displays include a colourful LCD matrix in TFT technology that is illuminated by light-emitting LEDs. With those solutions, we obtain a high screen brightness ratio. The XID displays are used as on-board passenger information system displays and advertising displays. They show information about the route, display adverts and any additional content that can be determined by the user. The device has an audio output for sound emitting.
